Chagnon Building & Remodeling says Gary Chagnon started the company in 1992 and that he and his son Patrick run it together, with Gary handling design and Patrick running construction. Its website lists Hadley, Northampton, Amherst, Belchertown, Holyoke, Easthampton, Westfield and Springfield as its service area. Its Massachusetts home improvement contractor license, number 112751, is active on the state registry. A recent customer said Patrick, Gary and Tye did a complete remodel of the main level of their 1960s home: windows, doors, a new kitchen, a new bathroom, floors, moved walls, and updated electrical and plumbing. That customer said the contract was detailed and the change orders were easy to understand. A recent Houzz customer said the company finished their attic and built their deck, and praised communication through the job portal it uses. A 2025 customer said Patrick and crew built their addition, and that he was communicative about changes, delays and progress. In a 2025 review, a customer said the company did a bathroom remodel and finished their basement. A 2025 customer said the company redid their deck, kept the area clean and wrapped up on time. A 2024 customer said the company built a two-car garage, with a design made to reflect their needs and budget. A 2019 Houzz customer said the company remodeled their kitchen and that its online job portal let them see what happened each day and what was coming next. A 2018 Houzz customer said Gary and crew handled replacement windows, a new bathroom vanity and some repairs. A 2018 Houzz customer described a kitchen remodel and a bathroom remodel that went badly: that customer said they were charged change orders when the foundation work took longer than planned, went without a working toilet for over a month, and learned from the city building inspector that he had quit. That 2018 customer said two later contractors hired to clean up the work saw cut corners.
Very pleased with Patrick, Gary and Tye. They take pride and their workmanship. Their contract is extremely detailed, change orders are easily understood, and they -the entire team- is trustworthy. They did a complete remodel of the main level of our 1960’s home. Windows, doors, new kitchen, new bathroom, floors, moved walls, updated electrical and plumbing. It was a very extensive remodel. Would hire them again.
CBR finished our attic as well as built our deck. Great communication through the job portal they use, top quality craftsmanship, and very easy to work with. Highly recommend!
Fantastic! Patrick and crew did an amazing job with our addition from start to finish. He listened carefully to what we wanted, offering opinions and advice based on years of experience. He worked hard to make sure we had the best materials for the best price. He was patient when I asked for new or different things, and was always communicative with changes, if there were any unavoidable delays, and progress on the project. I would absolutely contract with them again.
We’ve worked with Chagnon Building and Remodeling for two major home renovation projects: A bathroom remodel and a finishing of the basement. We had excellent experiences both times. The quality of the work is detailed and high. All the crafts workers are skilled and attentive to detail. They are a family run business and easy to communicate with, answer questions promptly, and Problem solve any issues that come up along the way. Highly recommend!
I had Chagnon Building and Remodeling redo my deck recently, and they did an awesome job. From the beginning, they were super easy to work with—really responsive, helpful with ideas, and made the whole process smooth. The new deck looks great and feels really solid. You can tell they take pride in their work because everything was done with care and attention to detail. They also kept the area clean and made sure everything was wrapped up on time, which I really appreciated. Overall, I’m really happy with how it turned out and would definitely recommend them if you’re looking to update your deck or do any kind of remodeling work. Great people, great work!
